Although both technologies perform the same basic function, they are very different in terms of their construction techniques, materials, and performance under various conditions, so it’s important to understand the potential impact of selecting one over the other.Understanding the inherent characteristics of both tantalum capacitors and MLCCs, including their reliability and behavior with temperature and voltage, typical testing capabilities, and the latest developments for each will help ensure sound selections.The basic formula for capacitance is C = εr * ε0 * (A/d), in which,Tantalum capacitors achieve high capacitance values through a combination of factors, including a tantalum pentoxide (Ta,For surface-mount applications, AVX manufactures two styles of tantalum capacitors, both of which incorporate an MnO.In contrast to tantalum capacitors, ceramic capacitors have less overall plate area and significantly thicker layers, but compensate for such deficiencies by using dielectric materials with a much higher dielectric constant. Standard Capacitor Values & Color Codes Over time, a series of standard capacitor values have evolved, just as with resistors and inductors. Some capacitors are designed specifically for low-ESR, but manufacturers of aluminium electrolytic capacitors do not specify ESR consistently. For instance, ceramic capacitors made using X5R dielectric materials have an operating temperature range of -55°C to +85°C with an allowable variation in capacitance of ±15% over that range and exhibit non-linear capacitance value stability over that range.Similarly, any material that allows a device to meet or exceed the X7R temperature characteristics, ±15% capacitance variation over a temperature range of -55°C to +125°C, can be called X7R.

Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. In addition, both moisture resistance and thermal shock testing resulting in stable performance for both technologies.In conclusion, both tantalum and ceramic capacitors offer several advantages and benefits that aid in the manufacturing of efficient, high-reliability electronics across a wide range of markets. The marking of a bar is used to denote the polarity of the capacitor indicating the negative terminal. Tantalum capacitors do not experience similar aging and have no known wear-out mechanism.Insulation resistance is the resistance measured across the dielectric of a capacitor. CAT# DT-25.
